Blockade-Running Between Europe and the Far East by Submarines, 1942-44
[SRH-019]

Blockade-Running Between Europe and the Far East by Submarines, 1942-44

1. Blockade-running by submarines

a. Blockade-running between German Europe and the Far East, which began in 1941, at first was carried on exclusively by merchant vessels operated by the Germans. The venture enjoyed considerable initial success, but in the 1942-43 season (September 1942-March 1943) the losses to the blockade-running fleet were so severe that by January of this year the Germans decided to discontinue the use of surface vessels. A summary of the record of the surface blockade-runners is annexed as TAB A.

b. So far as is known, the first submarine to run the blockade made the voyage in the middle of 1942. However, it was not until well into 1943 that the Axis attempted to use submarines regularly as blockade-runners. In the spring of 1943 the German Navy converted seven large Italian submarines to cargo-carriers for the purpose of running the blockade. In addition to the converted Italian craft, at least three Japanese and a considerable number of German operational submarines have been used to carry cargo and passengers to and from the Far East.

c. It is believed that up to November of this year 35 submarines departed from Europe for the Far

East (see TAB B). During the same period at least 11 submarines are believed to have left Far Eastern ports for Europe (see TAB C). A summary of the record of blockade-running by submarine in both directions is as follows:

d. To date, the submarines employed as bkockade-runners have ranged from German operational craft of 740 tons to cargo-carriers of approximately 2,200 tons. The cargoes have varied in size from approximately 80 tons to a maximum of about 300 tons. The total volume of goods carried in both directions in 26 successfrul voyages has been less than

**Includes the I-29, which arrived safely in July at Singapore, where her passengers disembarked, but was later sunk with the loss of her cargo while en route to Japan.

the cargo which could be carried on one of the surface blockade-runners formerly used.

e. Although the sailings of surface blockade-runners occurred principally in the autumn and winter months, so as to enable the vessels to negotiate the Bay of Biscay area when short days and weather conditions hamper observation, submarines are used at all seasons of the year. Surface blockade-runners used French ports exclusively; although most of the blockade-running submarines have departred from, or arrived at, Biscay ports, at least seven of them have used German and Norwegian ports.

f. Submarine voyages between Europe and the Far East require a minimum of from two to three months. Frequently, however, more time is consumed, since certain of the German submarines, carrying small cargoes, engage in operations in the Atlantic and Indian Oceans while en route.*

g. At least 10 German submarines are believed to be east of Capetown (as of 11 Nov 44), either engaged in operations or making preprations for the return trip. A list of those German submarines follows:


*Some of the German submarines have also engaged in operations in the Far East between voyages.

2. Cargoes from Europe to the Far East:

a. After the Germans suspended blockade-running by surface vessels in January 1944, the Japanese decided to sell, lease or otherwise return to the Germans and Italians such items as rolling mill equipment, presses, machine tools, prototypes of large guns, samples of aircraft, etc., which they wanted but which could not be shipped by submarine. The principal goods retained for shipment for the Far East included the following:

      German radar units and other electronic equipment
      Bombsights
      Vacuum tubes
      Optical glass
      Steel balls
      Mercury
      Machine gun ammunition

      Prototypes of communications equipment
      High grade aluminum
      Special alloy steel for aircraft motors
      Chemicals and drugs
      Platinum
      Industrial diamonds
      Plans and drawings for weapons, aircraft, etc.

b. TAB D lists the items known to have been shipped by submarine from Europe to the Far East in the period 1942-44. Other goods wanted by the Japanese, but known to have been destroyed at Lorient by the Germans last summer because of the speed of the Allied advance, are lsited in TAB E. TAB F contains a list of products not known to have been shipped, but believed to have been available somewhere in Europe for shipment to the Far East before the last known departure.

c. In addition to the cargoes carried to the Far East, a number of German and Japanese engineers, technical experts and diplomatic officials have traveled on blockade-running submarines as passengers. The names of such passengers are listed in TAB G.

3. Cargoes from the Far East to Europe:

a. As indicated above, so far as is known there have been but six successful voyages of blockade-running submarines from the Far East in the period from 1942 to November 1944. Little information is available concerning

the cargoes those vessels actually carried. However, it is known that from the inauguration of Axis blockade-running in 1941 the Germans have made great efforts to get such Far Eastern products as rubber, tungsten, tin, molybdenum, quinine and opium, and that the cargoes carried by submarines have actually included those items. During the past year the Germans have been particularly anxious to get tungsten, molybdenum and tin, and have used operational submarines returning to Europe to carry those commodities. Since the Germans need large quantities of the products they have tried to get from the Far East, the small amounts of such products that they could have received by submarines have probably been of little assistance to them. Further information about items transported from the Far East is to be found in TAB H.

b. The Japanese have taken advantage of submarine transportation to send personnel to Europe, principally (i) diplomatic offices and (ii) technicians to study the latest German developments in scientific fields. TAB I gives a list of persons known to have been carried as passengers on submarines from the Far East.
